SI'NKER FOR SYRINGE-TUBES.

SPECIFICATION forming part of Letters Patent No. 475,495, dated May 24,1892. Application filed March 19, 1892. Serial No. 425,539. (No model.)

To a/ZZ whom it may concern,.-

Be it known thatl, ANTON O.EGGERs,aciti Zen of the United States, and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Sinkers for Syringe-Tubes, of which the following is a specification.

This invention relates to an improved sinker for the lower ends ofsyringe-tubes, which is made of ring shape, so as to be used forsuspending the syringe-tube when not, required for use; and it consistsof a sinker for syringetubes which is made ring-shaped and with tubularends, one side of the ring shaped sinker being made solid while theother side is provided with a channel that connects the tubular ends,said channel being produced by means of an elastic coring when moldingthe sinker before vulcanization.

In the accompanying drawings, Figure 1 represents a side view of myimproved sinker for syringe-tubes, and Fig. 2 is a vertical longitudinalsection of the same.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the sinker, which is made ofring shape and provided with tubular ends et a at diametricallyoppositepoints, the upper end a being provided with a collar b', against whichthe lower end of the syringe-tube B abuts when the same is placed overthe said upper end a of the sinker. The lower tubular end ct of thesinker A is serrated at its lower edges, so as to facilitate the ingressand egress of the liquid when the sinker is in vertical position inthe-vessel from which the liquid is supplied to the syringe. Thering-shaped body of the sinker is made solid along one side of the sameand at the opposite side is provided with a tubular channel b. thatconnects the tubular ends a a', the tubular channel and ends beingformed by means of an elastic core, whichis inserted beforevulcanization in the mold in which the sinkeris formed, said elasticcore being removed after the vulcanization is completed. In this mannera continuous passage for the liquid is formed along one side of thesinker, while sufficient weight is given to the sinker by the remainingsolid portion of the same, and at the same time bythe ring shape of thesinker the same can be used for suspending the syringe from the sinkerafter use, so as to produce the draining of the liquid and the drying ofthe syringe.

Having thus described my invention, IY

claim as new and desire to secure by Letters Patent- A sinker forsyringe-tubes, composed of a ring-shaped body having tubular ends and achannel extending along one side of the ringshaped sinker and connectingwith the tubular ends, while the remaining portion of the sinker issolid, substantially as set forth.

In testimony that l claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
